表4 家畜肠道发酵温室气体检测方法的优缺点

Table 4 Advantages and disadvantages of greenhouse gas detection methods for the intestinal fermentation of domestic animals

检测方法 Testing method 优点 Advantages 缺点 Disadvantages 呼吸代谢箱法 Respiratory metabolism box method 发展较为成熟,应用广泛;可精确的测量肠道发酵产生的甲烷 Mature development and wide application; Accurate measurement of methane produced by intestinal fermentation 不能真实反映家畜体外的自然环境;构造和维修费用昂贵 Unable to reflect the external natural environment of livestock; High cost 六氟化硫示踪法 sulfur hexafluoride tracer method 投资和运行费用低;可进行群体检测 Low investment and operating costs; Group detection 发展不够成熟,仪器设备有待改进 Instruments and equipment need to be improved 头罩法和面罩法 Headcover and mask method 成本低 Low cost 低估甲烷产量;准确度不高;使用具有局限性 Understating methane production; Low accuracy; Limitations of usage
